The Toyota Izoa is a compact crossover SUV sold in select markets. Like most modern vehicles, it comes equipped with a Tire Pressure Monitoring System (TPMS) to alert drivers of low tire pressure. Properly maintaining and resetting the TPMS is crucial for vehicle safety and performance. This comprehensive guide will walk you through the process of resetting and relearning the TPMS on Toyota Izoa models across all generations.

Understanding TPMS in Toyota Vehicles

Before diving into the specific reset procedures, it’s important to understand how TPMS works in Toyota vehicles like the Izoa:

What is TPMS?

TPMS stands for Tire Pressure Monitoring System. It’s an electronic system designed to monitor the air pressure inside pneumatic tires on various types of vehicles. The system reports real-time tire pressure information to the driver, usually through a gauge or low-pressure warning light.

Types of TPMS Used by Toyota

Toyota utilizes two main types of TPMS:

1. Direct TPMS: Uses pressure sensors inside each tire to directly measure air pressure.
2. Indirect TPMS: Uses wheel speed sensors to infer tire pressure based on rotational differences between wheels.

The Toyota Izoa typically uses a direct TPMS system, which provides more accurate pressure readings but requires specific procedures for resetting and relearning.

When to Reset or Relearn TPMS

You’ll need to reset or relearn the TPMS on your Toyota Izoa in the following situations:

• After rotating tires
• When replacing one or more tires
• After replacing a TPMS sensor
• When the TPMS warning light remains on after inflating tires to the correct pressure
• After disconnecting or replacing the vehicle’s battery

General TPMS Reset Procedure for Toyota Izoa

While specific steps may vary slightly between generations, here’s a general procedure for resetting the TPMS on a Toyota Izoa:

1. Ensure all tires are inflated to the correct pressure (check the driver’s side door jamb for the correct PSI)
2. Turn the ignition to the “ON” position without starting the engine
3. Locate the TPMS reset button (usually under the steering wheel or in the glove box)
4. Press and hold the TPMS reset button until the tire pressure light blinks three times
5. Start the engine and wait for about 20 minutes
6. The system will now reset and the TPMS light should turn off

TPMS Reset and Relearn Procedures by Generation

Let’s break down the specific procedures for each generation of the Toyota Izoa:

First Generation Toyota Izoa (2018-2022)

The first generation Toyota Izoa was introduced in 2018 and shares its platform with the Toyota C-HR. For this generation:

1. Ensure all tires are properly inflated
2. Turn the ignition to “ON” without starting the engine
3. Press and hold the TPMS reset button (located under the steering wheel) for about 3 seconds
4. The TPMS light will flash 3 times to confirm the reset initiation
5. Start the engine and drive the vehicle at 50 km/h (31 mph) or more for at least 10 minutes
6. The system will calibrate and the TPMS light should turn off

If the light doesn’t turn off after this procedure, you may need to use a TPMS relearn tool to register new sensor IDs.

Second Generation Toyota Izoa (2023-Present)

The second generation Toyota Izoa, introduced in 2023, features an updated TPMS system. Here’s how to reset it:

1. Inflate all tires to the correct pressure
2. Turn the ignition to “ON”
3. Using the multi-information display controls on the steering wheel, navigate to the “Vehicle Settings” menu
4. Select “TPMS” and then “Set Pressure”
5. Press and hold the “OK” button until the TPMS light blinks 3 times
6. Start the engine and drive for about 10 minutes at speeds over 25 mph
7. The system will calibrate and the TPMS light should turn off

For this generation, Toyota has integrated the TPMS reset function into the vehicle’s infotainment system, making it more user-friendly.

Using a TPMS Relearn Tool

In some cases, especially after replacing TPMS sensors, you may need to use a specialized TPMS relearn tool. Here’s how to use one on a Toyota Izoa:

1. Connect the TPMS relearn tool to the vehicle’s OBD-II port
2. Turn the ignition to “ON” without starting the engine
3. Use the tool to scan for existing sensor IDs
4. If new sensors are installed, use the tool to program their IDs into the vehicle’s ECU
5. Follow the tool’s prompts to complete the relearn procedure
6. Start the engine and drive the vehicle to ensure the TPMS light turns off

Popular TPMS relearn tools for Toyota vehicles include the Autel TS501 and the ATEQ VT55.

Troubleshooting TPMS Issues

If you’re having trouble resetting or relearning the TPMS on your Toyota Izoa, consider these common issues and solutions:

Maintaining Your Toyota Izoa’s TPMS

To keep your TPMS functioning properly and avoid frequent resets:

• Check tire pressure monthly and before long trips
• Rotate tires according to the maintenance schedule (usually every 5,000-8,000 miles)
• Replace TPMS sensors when replacing tires (sensors typically last 5-7 years)
• Have the TPMS inspected during regular vehicle maintenance
• Avoid using tire sealants, which can damage TPMS sensors

The Importance of Proper Tire Pressure

Maintaining correct tire pressure is crucial for several reasons:

• Improved fuel efficiency
• Extended tire life
• Better handling and braking performance
• Reduced risk of tire failure
• Enhanced overall vehicle safety

The TPMS in your Toyota Izoa helps ensure your tires are always at the optimal pressure, but it’s still important to manually check pressure regularly.

TPMS Regulations and Toyota Compliance

TPMS became mandatory in many countries due to safety concerns:

• In the United States, the TREAD Act of 2000 required all light motor vehicles to have TPMS by 2008
• The European Union mandated TPMS on all new passenger cars from November 2014
• In Japan, TPMS has been mandatory on all new passenger vehicles since 2018

Toyota, including models like the Izoa, complies with these regulations by equipping their vehicles with advanced TPMS technology.

Future of TPMS Technology in Toyota Vehicles

As automotive technology advances, TPMS systems are evolving too. Future Toyota models, including upcoming Izoa generations, may feature:

• Integration with advanced driver assistance systems (ADAS)
• Predictive tire maintenance alerts
• Wireless sensor charging
• Enhanced accuracy in extreme temperatures
• Integration with vehicle-to-everything (V2X) communication systems

These advancements will likely make TPMS systems more reliable and user-friendly, potentially simplifying the reset and relearn procedures.

Conclusion

Properly maintaining and resetting the TPMS on your Toyota Izoa is crucial for safety, performance, and compliance with vehicle regulations. While the specific procedures may vary slightly between generations, the general process involves resetting the system through a combination of button presses and driving cycles.

Remember to reset your TPMS after tire rotations, replacements, or any service that might affect tire pressure. If you’re unsure about any step in the process, consult your vehicle’s owner’s manual or seek assistance from a qualified Toyota technician.

By keeping your TPMS properly calibrated, you ensure that your Toyota Izoa can accurately monitor tire pressure, contributing to a safer and more efficient driving experience.
